# Polyfills #
Angular is built on the latest standards of the web platform.
Targeting such a wide range of browsers is challenging because they do not support all features of modern browsers.
You compensate by loading polyfill scripts ("polyfills") on the host web page (`index.html`)
that implement missing features in JavaScript.
+makeExample('quickstart/ts/index.html', 'polyfills')(format='.')
:marked
A particular browser may require at least one polyfill to run _any_ Angular application.
You may need additional polyfills for specific features.
The tables below will help you determine which polyfills to load, depending on the browsers you target and the features you use.
.alert.is-important
:marked
The suggested polyfills are the ones we know will run full Angular applications.
You may need additional polyfills to support features not covered by this list.
Note that polyfills cannot magically transform an old, slow browser into a modern, fast one.

## Mandatory polyfills ##
These are the polyfills required to run an Angular application on each supported browser:
table
tr(style="vertical-align: top")
th Browsers (desktop & mobile)
th Polyfills required
tr(style="vertical-align: top")
td Chrome, Firefox, Edge, Safari 9+
td None
tr(style="vertical-align: top")
td Safari 7 & 8, IE10 & 11, Android 4.1+
td
:marked
[ES6](#core-es6)
tr(style="vertical-align: top")
td IE9
td
:marked
[ES6<br>classList](#classlist)
:marked
## Optional browser features to polyfill ##
Some features of Angular may require additional polyfills.
For example, the animations library relies on the standard web animation API, which is only available in Chrome and Firefox today.
You'll need a polyfill to use animations in other browsers.
Here are the features which may require additional polyfills:
table
tr(style="vertical-align: top")
th Feature
th Polyfill
th(style="width: 50%") Browsers (desktop & mobile)
tr(style="vertical-align: top")
td
a(href="./animations.html") Animations
td

[Web Animations](#web-animations)
td All but Chrome and Firefox<br>Not supported in IE9
tr(style="vertical-align: top")

a(href="../api/common/index/CurrencyPipe-class.html" target="_blank") currency
